CHAPTER 1
Introducing the ZyWALL
This chapter gives an overview of the ZyWALL. It explains the front panel ports,
LEDs, introduces the management methods, and lists different ways to start or
stop the ZyWALL.
1.1 Overview and Key Default Settings
The ZyWALL is a comprehensive security device. Its flexible configuration helps
network administrators set up the network and enforce security policies efficiently.
In addition, the ZyWALL provides excellent throughput, making it an ideal solution
for reliable, secure service.
The ZyWALL’s security features include VPN, firewall, content filtering, ADP
(Anomaly Detection and Protection), and certificates. It also provides bandwidth
management, Instant Messaging (IM) and Peer to Peer (P2P) control, NAT, port
forwarding, policy routing, DHCP server and many other powerful features.
Flexible configuration helps you set up the network and enforce security policies
efficiently. See Chapter 2 on page 37 for a more detailed overview of the ZyWALL’s
features.
The ZyWALL provides excellent throughput with the reliability of dual WAN Gigabit
Ethernet ports and load balancing. You can also use a 3G cellular USB (not
included) for a third WAN connection.
The ZyWALL lets you set up multiple networks for your company. The DeMilitarized Zone (DMZ) increases LAN security by providing separate ports for
connecting publicly accessible servers. The ZyWALL also provides two separate
LAN networks. You can set ports to be part of the LAN1, WLAN, or DMZ.
Alternatively, you can deploy the ZyWALL as a transparent firewall in an existing
network with minimal configuration.
1.2 Wall-mounting
Do the following to attach your ZyWALL to a wall.
ZyWALL USG 20/20W User’s Guide
29
Chapter 1 Introducing the ZyWALL
USG 20
1 Screw the two screws provided with your ZyWALL into the wall 150 mm apart (see
the figure in step 2). Use screws with 6 mm ~ 8 mm (0.24" ~ 0.31") wide heads.
Do not screw the screws all the way in to the wall; leave a small gap between the
head of the screw and the wall.
The gap must be big enough for the screw heads to slide into the screw slots and
the connection cables to run down the back of the ZyWALL.
Note: Make sure the screws are securely fixed to the wall and strong enough to hold
the weight of the ZyWALL with the connection cables.
2 Align the holes on the back of the ZyWALL with the screws on the wall. Hang
the ZyWALL on the screws.

1.5 Starting and Stopping the ZyWALL
Here are some of the ways to start and stop the ZyWALL.
Always use Maintenance > Shutdown > Shut down or the shutdown
command before you turn off the ZyWALL or remove the power. Not
doing so can cause the firmware to become corrupt.
Table 3 Starting and Stopping the ZyWALL
METHOD DESCRIPTION
Turn i n g on the
power
Rebooting the
ZyWALL
Using the RESET
button
A cold start occurs when you turn on the power to the ZyWALL. The
ZyWALL powers up, checks the hardware, and starts the system
processes.
A warm start (without powering down and powering up again)
occurs when you use the Reboot button in the Reboot screen or
when you use the reboot command. The ZyWALL writes all cached
data to the local storage, stops the system processes, and then does
a warm start.
If you press the RESET button, the ZyWALL sets the configuration
to its default values and then reboots.

CHAPTER 2
Features and Applications
This chapter introduces the main features and applications of the ZyWALL.
2.1 Features
The ZyWALL’s security features include VPN, firewallcontent filtering, ADP
(Anomaly Detection and Protection), and certificates. It also provides bandwidth
management, NAT, port forwarding, policy routing, DHCP server and many other
powerful features.
The rest of this section provides more information about the features of the
ZyWALL.
High Availability
To ensure the ZyWALL provides reliable, secure Internet access, set up one or
more of the following:
• Multiple WAN ports and configure load balancing between these ports.
• One or more 3G (cellular) connections.
Virtual Private Networks (VPN)
Use IPSec, SSL to provide secure communication between two sites over the
Internet or any insecure network that uses TCP/IP for communication. The
ZyWALL also offers hub-and-spoke IPSec VPN.
Flexible Security Zones
Many security settings are made by zone, not by interface, port, or network. As a
result, it is much simpler to set up and to change security settings in the ZyWALL.
You can create your own custom zones. You can add interfaces and VPN tunnels to
zones.
ZyWALL USG 20/20W User’s Guide
37
Chapter 2 Features and Applications
Firewall
The ZyWALL’s firewall is a stateful inspection firewall. The ZyWALL restricts access
by screening data packets against defined access rules. It can also inspect
sessions. For example, traffic from one zone is not allowed unless it is initiated by
a computer in another zone first.
Anomaly Detection and Prevention (ADP)
ADP (Anomaly Detection and Prevention) can detect malicious or suspicious
packets and respond instantaneously. It can detect:
• Anomalies based on violations of protocol standards (RFCs – Requests for
Comments)
• Abnormal flows such as port scans.
The ZyWALL’s ADP protects against network-based intrusions. See Section 29.3.4
on page 472 and Section 29.3.5 on page 475 for more on the kinds of attacks that
the ZyWALL can protect against. You can also create your own custom ADP rules.
Bandwidth Management
Bandwidth management allows you to allocate network resources according to
defined policies. This policy-based bandwidth allocation helps your network to
better handle applications such as Internet access, e-mail, Voice-over-IP (VoIP),
video conferencing and other business-critical applications.
Content Filter
Content filtering allows schools and businesses to create and enforce Internet
access policies tailored to the needs of the organization.
You can also subscribe to category-based content filtering that allows your
ZyWALL to check web sites against an external database of dynamically-updated
ratings of millions of web sites. You then simply select categories to block or
monitor, such as pornography or racial intolerance, from a pre-defined list.
Anti-Spam
The anti-spam feature can mark or discard spam. Use the white list to identify
legitimate e-mail. Use the black list to identify spam e-mail. The ZyWALL can also
check e-mail against a DNS black list (DNSBL) of IP addresses of servers that are
suspected of being used by spammers.
38
ZyWALL USG 20/20W User’s Guide
2.2 Applications

5.5.5 VPN Advanced Wizard - Phase 1 Settings
There are two phases to every IKE (Internet Key Exchange) negotiation – phase 1
(Authentication) and phase 2 (Key Exchange). A phase 1 exchange establishes an
IKE SA (Security Association).
Figure 45 VPN Advanced Wizard: Phase 1 Settings
• Secure Gateway: If Any displays in this field, it is not configurable for the
chosen scenario. If this field is configurable, enter the WAN IP address or
domain name of the remote IPSec device (secure gateway) to identify the
remote IPSec device by its IP address or a domain name. Use 0.0.0.0 if the
remote IPSec device has a dynamic WAN IP address.
• My Address (interface): Select an interface from the drop-down list box to
use on your ZyWALL.
• Negotiation Mode: Select Main for identity protection. Select Aggressive to
allow more incoming connections from dynamic IP addresses to use separate
passwords.
Note: Multiple SAs connecting through a secure gateway must have the same
negotiation mode.
• Encryption Algorithm: 3DES and AES use encryption. The longer the key, the
higher the security (this may affect throughput). Both sender and receiver must
know the same secret key, which can be used to encrypt and decrypt the
message or to generate and verify a message authentication code. The DES
encryption algorithm uses a 56-bit key. Triple DES (3DES) is a variation on DES
82
ZyWALL USG 20/20W User’s Guide
Chapter 5 Quick Setup
that uses a 168-bit key. As a result, 3DES is more secure than DES. It also
requires more processing power, resulting in increased latency and decreased
throughput. AES128 uses a 128-bit key and is faster than 3DES. AES192 uses a
192-bit key and AES256 uses a 256-bit key.
• Authentication Algorithm: MD5 gives minimal security. SHA-1 gives higher
security. MD5 (Message Digest 5) and SHA1 (Secure Hash Algorithm) are hash
algorithms used to authenticate packet data. The SHA1 algorithm is generally
considered stronger than MD5, but is slower.
• Key Group: DH5 is more secure than DH1 or DH2 (although it may affect
throughput). DH1 (default) refers to Diffie-Hellman Group 1 a 768 bit random
number. DH2 refers to Diffie-Hellman Group 2 a 1024 bit (1Kb) random number.
DH5 refers to Diffie-Hellman Group 5 a 1536 bit random number.
• SA Life Time: Set how often the ZyWALL renegotiates the IKE SA. A short SA
life time increases security, but renegotiation temporarily disconnects the VPN
tunnel.
• NAT Traversal: Select this if the VPN tunnel must pass through NAT (there is a
NAT router between the IPSec devices).
Note: The remote IPSec device must also have NAT traversal enabled. See VPN,
NAT, and NAT Traversal on page 419 for more information.
• Dead Peer Detection (DPD) has the ZyWALL make sure the remote IPSec
device is there before transmitting data through the IKE SA. If there has been
no traffic for at least 15 seconds, the ZyWALL sends a message to the remote
IPSec device. If it responds, the ZyWALL transmits the data. If it does not
respond, the ZyWALL shuts down the IKE SA.
• Authentication Method: Select Pre-Shared Key to use a password or
Certificate to use one of the ZyWALL’s certificates.

• Active Protocol: ESP is compatible with NAT, AH is not.
• Encapsulation: Tunnel is compatible with NAT, Transport is not.
• Encryption Algorithm: 3DES and AES use encryption. The longer the AES
key, the higher the security (this may affect throughput). Null uses no
encryption.
• Authentication Algorithm: MD5 gives minimal security. SHA-1 gives higher
security. MD5 (Message Digest 5) and SHA1 (Secure Hash Algorithm) are hash
algorithms used to authenticate packet data. The SHA1 algorithm is generally
considered stronger than MD5, but is slower.
• SA Life Time: Set how often the ZyWALL renegotiates the IKE SA. A short SA
life time increases security, but renegotiation temporarily disconnects the VPN
tunnel.
• Perfect Forward Secrecy (PFS): Disabling PFS allows faster IPSec setup, but is
less secure. Select DH1, DH2 or DH5 to enable PFS. DH5 is more secure than
DH1 or DH2 (although it may affect throughput). DH1 refers to Diffie-Hellman
Group 1 a 768 bit random number. DH2 refers to Diffie-Hellman Group 2 a 1024
bit (1Kb) random number. DH5 refers to Diffie-Hellman Group 5 a 1536 bit
random number (more secure, yet slower).
• Local Policy (IP/Mask): Type the IP address of a computer on your network.
You can also specify a subnet. This must match the remote IP address
configured on the remote IPSec device.
• Remote Policy (IP/Mask): Type the IP address of a computer behind the
remote IPSec device. You can also specify a subnet. This must match the local
IP address configured on the remote IPSec device.
• Nailed-Up: This displays for the site-to-site and remote access client role
scenarios. Select this to have the ZyWALL automatically renegotiate the IPSec
SA when the SA life time expires.

CHAPTER 6
Configuration Basics
This information is provided to help you configure the ZyWALL effectively. Some of
it is helpful when you are just getting started. Some of it is provided for your
reference when you configure various features in the ZyWALL.
• Section 6.1 on page 87 introduces the ZyWALL’s object-based configuration.
• Section 6.2 on page 88 introduces zones, interfaces, and port groups.
• Section 6.3 on page 91 introduces some terminology and organization for the
ZyWALL.
• Section 6.4 on page 91 covers the ZyWALL’s packet flow.
• Section 6.5 on page 95 identifies the features you should configure before and
after you configure the main screens for each feature. For example, if you want
to configure a trunk for load-balancing, you should configure the member
interfaces before you configure the trunk. After you configure the trunk, you
should configure a policy route for it as well. (You might also have to configure
criteria for the policy route.)
• Section 6.6 on page 103 identifies the objects that store information used by
other features.
• Section 6.7 on page 105 introduces some of the tools available for system
management.
6.1 Object-based Configuration
The ZyWALL stores information or settings as objects. You use these objects to
configure many of the ZyWALL’s features and settings. Once you configure an
object, you can reuse it in configuring other features.
When you change an object’s settings, the ZyWALL automatically updates all the
settings or rules that use the object. For example, if you create a schedule object,
you can have firewall, content filter, and other settings use it. If you modify the
schedule, all the firewall, content filter, and other settings that use the schedule
automatically apply the updated schedule.
You can create address objects based on an interface’s IP address, subnet, or
gateway. The ZyWALL automatically updates every rule or setting that uses these
objects whenever the interface’s IP address settings change. For example, if you

change an Ethernet interface’s IP address, the ZyWALL automatically updates the
rules or settings that use the interface-based, LAN subnet address object.
You can use the Configuration > Objects screens to create objects before you
configure features that use them. If you are in a screen that uses objects, you can
also usually select Create new Object to be able to configure a new object. For a
list of common objects, see Section 6.6 on page 103.
Use the Object Reference screen (Section 3.3.3.3 on page 53) to see what
objects are configured and which configuration settings reference specific objects.
6.2 Zones, Interfaces, and Physical Ports
Zones (groups of interfaces and VPN tunnels) simplify security settings. Here is an
overview of zones, interfaces, and physical ports in the ZyWALL.

Ethernet Ports
(P1, P2, ...)
A zone is a group of interfaces and VPN tunnels. Use zones to apply
security settings such as firewall, remote management.
Interfaces are logical entities that (layer-3) packets pass through.
Use interfaces in configuring VPN, zones, trunks, DDNS, policy
routes, static routes, HTTP redirect, and NAT.
Port roles combine physical ports into interfaces.
The physical port is where you connect a cable. In configuration, you
use physical ports when configuring port groups. You use interfaces
and zones in configuring other features.
ZyWALL USG 20/20W User’s Guide
6.2.1 Interface Types
There are many types of interfaces in the ZyWALL. In addition to being used in
various features, interfaces also describe the network that is directly connected to
the ZyWALL.
• Ethernet interfaces are the foundation for defining other interfaces and
network policies. You also configure RIP and OSPF in these interfaces.
• Port groups create a hardware connection between physical ports at the layer2 (data link, MAC address) level. Port groups are created when you use the
Interface > Port Roles screen to set multiple physical ports to be part of the
same (lan1, lan2 or dmz) interface.
• PPP interfaces support Point-to-Point Protocols (PPPoE or PPTP). ISP accounts
are required for PPPoE/PPTP interfaces.
• VLAN interfaces recognize tagged frames. The ZyWALL automatically adds or
removes the tags as needed. Each VLAN can only be associated with one
Ethernet interface.
• Bridge interfaces create a software connection between Ethernet or VLAN
interfaces at the layer-2 (data link, MAC address) level. Then, you can configure
the IP address and subnet mask of the bridge. It is also possible to configure
zone-level security between the member interfaces in the bridge.
Chapter 6 Configuration Basics
• Virtual interfaces increase the amount of routing information in the ZyWALL.
There are three types: virtual Ethernet interfaces (also known as IP alias),
virtual VLAN interfaces, and virtual bridge interfaces.

6.2.2 Default Interface and Zone Configuration
This section introduces the ZyWALL’s default zone member physical interfaces and
the default configuration of those interfaces. The following figure uses letters to
denote public IP addresses or part of a private IP address.

• The WAN zone contains the wan1 interface (physical port P1). It uses a public
IP address to connect to the Internet.
• The LAN1 zone contains the lan1 interface (a port group made up of physical
ports P2 and P3 on the ZyWALL). The LAN1 zone is a protected zone. The lan1
interface uses 192.168.1.1 and the connected devices use IP addresses in the
192.168.1.2 to 192.168.1.254 range.

Chapter 6 Configuration Basics
Traffic in > Defragmentation > Destination NAT > Routing > Stateful Firewall >
ADP > Application Classification > Content Filter > Anti-Spam > SNAT >

Figure 51 Packet Flow
The packet flow is as follows:
• Automatic SNAT and WAN trunk routing for traffic going from internal to
external interfaces (you don’t need to configure anything to all LAN to WAN
traffic).
The ZyWALL automatically adds all of the external interfaces to the default WAN
trunk. External interfaces include ppp and cellular interfaces as well as any
Ethernet interfaces that are set as external interfaces.
Examples of internal interfaces are any Ethernet interfaces that you configure as
internal interfaces.
• A policy route can be automatically disabled if the next-hop is dead.
• You do not need to set up policy routes for IPSec traffic.
• Policy routes can override direct routes.
• You do not need to set up policy routes for 1:1 NAT entries.
• You can create Many 1:1 NAT entries to translate a range of private network
addresses to a range of public IP addresses
• Static and dynamic routes have their own category.
6.4.1 Routing Table Checking Flow
92
When the ZyWALL receives packets it defragments them and applies destination
NAT. Then it examines the packets and determines how to route them. The
checking flow is from top to bottom. As soon as the packets match an entry in one
ZyWALL USG 20/20W User’s Guide
Chapter 6 Configuration Basics
of the sections, the ZyWALL stops checking the packets against the routing table
and moves on to the other checks, for example the firewall check.
Figure 52 Routing Table Checking Flow
1 Direct-connected Subnets: The ZyWALL first checks to see if the packets are
destined for an address in the same subnet as one of the ZyWALL’s interfaces. You
can override this and have the ZyWALL check the policy routes first by enabling
the policy route feature’s Use Policy Route to Override Direct Route option
(see Section 13.1 on page 297).
2 Policy Routes: These are the user-configured policy routes. Configure policy
routes to send packets through the appropriate interface or VPN tunnel. See
Chapter 13 on page 297 for more on policy routes.
3 1 to 1 and Many 1 to 1 NAT: These are the 1 to 1 NAT and many 1 to 1 NAT
rules. If a private network server will initiate sessions to the outside clients, create
a 1 to 1 NAT entry to have the ZyWALL translate the source IP address of the
server’s outgoing traffic to the same public IP address that the outside clients use
to access the server. A many 1 to 1 NAT entry works like multiple 1 to 1 NAT rules.
It maps a range of private network servers that will initiate sessions to the outside
clients to a range of public IP addresses. See Section 17.2.1 on page 340 for
more.
ZyWALL USG 20/20W User’s Guide
93
Chapter 6 Configuration Basics
4 Auto VPN Policy: The ZyWALL automatically creates these routing entries for the
VPN rules. Disabling the IPSec VPN feature’s Use Policy Route to control
dynamic IPSec rules option moves the routes for dynamic IPSec rules up above
the policy routes (see Section 23.2 on page 394).
5 Static and Dynamic Routes: This section contains the user-configured static
routes and the dynamic routing information learned from other routers through
RIP and OSPF. See Chapter 13 on page 297 for more information.
6 Default WAN Trunk: For any traffic coming in through an internal interface, if it
does not match any of the other routing entries, the ZyWALL forwards it through
the default WAN trunk. See Section 12.2 on page 292 for how to select which
trunk the ZyWALL uses as the default.
7 Main Routing Table: The default WAN trunk is expected to be used for any traffic
that did not match any earlier routing entries.
6.4.2 NAT Table Checking Flow
The checking flow is from top to bottom. As soon as the packets match an entry in
one of the sections, the ZyWALL stops checking the packets against the NAT table
and moves on to bandwidth management.

select an option to create a new object. After you create the object
you return to the main screen to finish configuring the feature.
You may not have to configure everything in the list of prerequisites.
For example, you do not have to create a schedule for a policy route
unless time is one of the criterion.
There are two uses for this.
These are other features you should usually configure or check right
after you configure the main screen(s) for this feature. For example,
you should usually create a policy route for a VPN tunnel.
You have to delete the references to this feature before you can delete
any settings. For example, you have to delete (or modify) all the
policy routes that refer to a VPN tunnel before you can delete the VPN
tunnel.
Note: PREQUISITES or WHERE USED does not appear if there are no prerequisites
or references in other features to this one. For example, no other features
reference DDNS entries, so there is no WHERE USED entry.
